"While the RTM may signal more earnest levels of testing within corporations, I predict very few CIOs are going to be implementing Vista on existing assets anytime in the next two or three quarters," Warren said. "And I would argue that most won't even allow it on new assets for at least six months, while the rest of the market catches up to Vista from a compatibility perspective."
Vista's hefty hardware requirements and Microsoft's decision to back-port many of Vista's technologies to Windows XP may restrain business deployments and new PC purchases, according to analyst Paul DeGroot of Directions on Microsoft, a newsletter in Kirkland, Wash. What's more, those that buy new PCs may slip Windows XP back on, since businesses tend to move to new platforms more slowly than consumers and value consistency, DeGroot added.
"Bringing Vista in on the replacement cycle will be the most common approach. Close to it, and possibly more popular, will be to bring Vista machines in and re-image them with volume XP," he said.
Vista is a "fairly radical departure from XP," DeGroot noted. "Customers know that testing of the first release was compressed and that a service pack or even a full replacement a few years down the road will make a big difference," he said. "An extraordinarily high number compared with previous OS releases of new Vista technologies have been or will be back-ported to the current OS."
Nevertheless, Vista will drive a major hardware refresh in businesses, according to analyst Peter O'Kelly of the Burton Group. He said major user-interface overhauls, search folders, security features, performance increases and a new programming model will translate into meaningful business benefits.
"There will be a pop. It won't be overnight, but a lot of companies that do their refresh will do their hardware, operating system and office [suite] all at one time," O'Kelley said. "This is a more significant upgrade and more substantive user benefit than XP."
However, other industry observers said it will be difficult to measure the market reaction until the rest of the Vista versions are released in late January.
As of Thursday afternoon, the Vista launch had no positive impact on Microsoft's stock. The company's share price displayed at $29.51 on the Nasdaq ticker just minutes before the press conference began and dipped to $29.47 two hours later.
